Question: Consider the multiple regression model with two regressors Upper X 1 and Upper X 2, where both variables are determinants of the dependent variable. You

Consider the multiple regression model with two regressors Upper X 1 and Upper X 2, where both variables are determinants of the dependent variable. You first regress Y on Upper X 1 only and find no relationship. However, when regressing Y on Upper X 1 and Upper X 2, the slope coefficient ModifyingAbove beta with caret 1 changes by a large amount. This suggests that your first regression suffers from: Part 2 A. dummy variable trap. B. perfect multicollinearity. C. heteroskedasticity. D. omitted variable bias
